I should add- you need to make the choice RIGHT NOW as to whether or not you are going to indulge this panic attack, or take the higher (and admittedly more difficult) road of just letting it go. As it said in one of Pan's recent posts, just say f*** it. If you let this anxiety get out of control, you will have a panic attack like you said. And that's no fun- in fact, panic attacks are terrible! We all know that. Think of your last one- you felt awful in it. Sometimes it actually feels like you're on the verge of insanity in a panic attack. You cry, you hyperventilate, you shake... and when it finally subsides, you're utterly exhausted and perhaps a little embarrassed. (At least, I'm always embarrassed... I'm just extrapolating here, though.) Luckily, it's entirely under your control whether you stop this harmful train of thought in its tracks right now. It is not worth whatever release you may get of it.
